Gwen usually takes a bus from her home to school. If she leaves home at 07 00, she will reach school at 08 30. Last week, a new MRT line has opened and she can take the train directly from home to school instead. This will shorten her journey by 15 min.
- How long does Gwen take to go school by the new MRT line?
- Gwen spent the next 8 h 55 min in school before dismissal. If Gwen started school at 07 40, at what time was she dismissed from school? Give your answer in the 12-hour clock format.
(a)
From 07 00 to 08 30: 1 h 30 min
Duration of Gwen's journey to go to school by the new MRT line
= 1 h 30 min - 15 min
= 90 min - 15 min
= 75 min
= 1 h 15 min
(b)
8 h 55 min after 07 40 = 16 35
16 35 = 4.35 p.m.
Time that Gwen was dismissed from school: 4.35 p.m.
Answer(s): (a) 1 h 15 min; (b) 4.35 p.m.
